SPECIFICATION forming part of Letters Patent No. 611,165, dated September 20, 1898.

Application filed December 15, 1897. Serial No. 662,064- (No model.)

To aZZ whom itmay' concern.-

Be it known that 1, WILLIAM ZEHNDER, a citizen of the United States, residing at Canal Dover, in the county ofTuscarawa-s and State of Ohio, have invented a new and useful Shutter-Operating Device, of which the following is a specification.

This invention relates to shutter-operating devices, its object being to provide a simple,

efficient, and durable mechanism to open and close the shutters from the inside of the window and also to open and close the pivoted slats of the shutter without opening the window.

With these objects in view the invention" consists of the details of construction, combination, and arrangement of parts, as will be hereinafter fully described, and particularly pointed out in the claims.

In the drawings, Figure 1 is a perspective shutter and slats being closed. Fig. 2 is an elevation showing the shutter closed and the slats'open. Fig. 3 is a horizontal section on the line on a; of Fig. 2. Fig. 4 is an elevation of the lower portion of the window-frame and shutter, looking at the inside. Fig. 5 is a vertical section through the knob and the inner end portions of the tube and shaft. Fig. 6 is a plan of the operating-gear. Fig. 7 is a plan of the cogged portion of the hinge member. Fig. 8 is a view of a detached detail. 7

Similar reference-numerals indicate similar parts in the several figures. I

1 indicates the window-frame, and 2 the shutter, both of which may be of any ordinary or approved construction. The hinge member attached to the shutter comprises a plate portion 3, having openings for the passage of screws 4., by means of which it is secured to the shutter, and from this plate portion ahorizontally-disposed fiat arm 5 extends, which is play between the cog-wheels.

sage of the securing-screws 9, and a horizontally disposed ear 10, which extends forwardly from the plate portion and is provided with an opening for the passage of the pintle 7. The arm 5 engages the lower face of the ear 10. The plate portion 8 isjprovided with a downward extension 11, preferably semicircular in form and provided with an opening 12, which serves as a bearing for the outer end of a tube 13. This tube extends horizontally through the window-frame, and a perforated plate 14 is secured to the inner face of the frame and forms a bearing for the inner end'of the tube. The tubeprojects at each end. beyond its bearings and is provided at its outer end with a collar 15, which engages the outer face of the extension 11. The arm 16 extends downwardly in a substantially vertical plane fromthe collarand has its lower end bent to form a horizontal arm 17, which is provided with an opening 18 at its outer end for a purpose to be hereinafter referred to.

19 indicates a shaft supported in the tube 13 to turn freely therein and, extending at each end beyond said tube. The shaft 19 carries at its outer end a bevel-gear 20, the flat wide cogs 21 of which mesh with the cogs 6 on the arm 5. The cogs 21 are wider than the cogs 6 and taper, their smaller ends being disposed oppositeand meshing with the gear formed by the teeth 6, and as the tapering'teeth 21 do not enter the spaces between the cogs 6 as far as possible there is a limited The object of this construction will be referred to hereinafter. The bevel-gear 20,will preferably be detachably secured on the shaft by means of :a threaded key having a slot in its outer end cated at 25, to fit the angular portion of the shaft 19, while the other portion 26 of the bore is cylindrical to fit over the tube, and the knob is adapted to move longitudinally on the tube and shaft. The end of the tube 13 is provided with a series of open-ended slots 27, adapted to receive the stem of a set-screw 28, fitted in the shank of the knob.

29 indicates a tubular bearing secured to the upper edge of the bottom rail 30 of the shutter, and 31 indicates ashaft supported to turn in said bearing. This shaft projects beyond the faces of the rail at each end and on the outside of the shutter is provided with a vertically-disposed arm 32 and on the inside of the shutter with a horizontally-disposed arm 33. Preferably the shaft 31 and arms 32 and 33 will be formed integrally from a piece of stout steel wire, although they may be sep arate pieces secured together in any suitable manner. The shaft 31 will be provided with a collar 31 at each end to engage the ends of the tubular bearing 29 to prevent longitudinal movement of the shaft therein. The lower end of the arm 32 is provided with an eye 34, and a link 35 is connected at one end to said eye and at its other end to the arm 17 through the opening 18. The connections between the link and arms 32 and 17 will be such as to permit pivotal movement, but practically no endwise movement of the link relatively to the said arms. The end of the arm 33 is bent to form an eye 36, in which one end of a link 37 is pivotally secured, and the other end of this link is pivotally connected to the slat-connecting rod 38 by means of a screw 39 or similar device.

40 indicates a spring-arm of any preferred form secured to the inner face of the shutter and adapted to frictionally engage a plate 41 on the window-sill to lock the shutter in its closed position.

42 indicates a hook pivoted on the plate 14: and is adapted to engage in one of the slots 27 when the knob is moved backwardto operate the shutter, its function being to lock the tube against turning with the shaft.

In operation the parts will be so arranged that when the shutter is closed the knob may be pushed forward on the tube and shaft to cause the screw 28 to engage in one of the slots 27, and. when so engaged the angular portion of the bore of the knob will be out of engagement with the angular portion of the shaft 19, and when the knob is turned only the tube 13 will turn withit. When the tube is turned, the arms 16 and 17 will move in the arc of a circle,which will result in giving a similar movement to the arm 33, and thereby move the slat-connecting rod 38 vertically and open or close the slats of the blind, according to the direction in which the knob is turned, and it is obvious that this operation can be accomplished withoutopening the window. The rotary movement of the tube is thus converted into vertical movement of the slat-connecting rod. When it is desired to open the shutter, the knob will be moved backward to bring the angular portion of its bore into engagement with the angular portion of the shaft 19, and when in this position the screw 28 will be out of engagement with the tube, and the shaft only will be turned when the knob is turned, it being understood that the hook 42 will have been engaged in one of the slots 27. It is obvious, therefore, that by turning the knob in the proper direction the shutter may be opened by means of the bevel-gear and the cogs on the hinge; also, that by reversing the movement of the knob the shutter can be closed, and in order to open or close the shutter it will not be necessary to open the window, since the spring-arm 40 and plate 41 will be engaged or disengaged by the movement of the shutter.

As the meshing portions of the cogs 21 of the bevel-gear 20 are only slightly narrower than the spaces between the cogs 6, the bevelgear 20 will have but little lost motion or play and will be capable of rotatingthc gear-wheel of the shutter; but should the shutter be moved on its hinges while the gear 20 is at rest the independent movement or play of the shutter cog-wheel will cause the gears to become wedged and will prevent further movement of the shutter. The cogs 21 and 6 will therefore act to lock the shutter in its open position, since the latter will be free to have only the slight movement necessary to cause the lost movement between one of the cogs 6 and one of the cogs 21.

It will be understood that changes in the form, proportion, and the minor details of construction may be resorted to without departing from the spirit or sacrificing any of the advantages of this invention.

Having thus described the invention, what I claim is 1. In a device of the class described, the combination of the vertical and horizontal gears designed to be mounted respectively on a window-casing and a shutter, and provided respectively with flat wide cogs and long narrow cogs, said cogs meshing with each other and capable of rotation to swing the shutter when the vertical gear-wheel is operated and forming a look when the vertical gear-wheel is at rest to prevent the shutter from swinging, substantially as described.

2. In a device of the class described, the combination of the hinge member attached to the shutter and provided with long narrow cogs on its lower face, a horizontal shaftsupported to turn in the window-frame, and projecting at each end beyond it, a bevel-gear carried on the outer end of the shaft and having flat wide cogs of greater width than those of the hinge member and meshing with the latter, the spaces between the cogs on the gear being wider than the cogs on the hinge member and the meshing portions of the cogs on the gear being slightly narrower than the spaces between the cogs of the hinge member, the gearing being adapted to swing the shutter when the bevel-gear is operated and forming a look when the bevel-gear is at rest to prevent the shutter from swinging, and a handhold on the inner end of the shaft to turn the latter, substantially as described.

3. The combination with a Window-frame, and a shutter having pivoted slats and provided with a slat-connecting rod, of a rockshaft journaled on the shutter and projecting beyond the inner and outer faces thereof and provided at its ends with arms, the inner arm being connected with the slat-connecting rod, an oscillating arm mounted on the Windowframe, a horizontal rod connecting the oscillating arm with the outer arm of the rockshaft, and means for oscillating the arm from the interior of the Window-frame, substantially as described.

4. The combination With a Window-frame, a slatted shutter and the slat-connecting rod thereof, of a shaft mounted to turn in said shutter and projecting at each end beyond the inner and outer faces of the shutter, a horizontally-disposed arm connected to the inner end of said shaft and having a link connection to the slat-connecting rod, a vertically-disposed arm connected to the outer end of the said shaft, a horizontal shaft supported to turn in the Window-frame and projecting at its ends beyond the inner and outer face thereof, a vertically-disposed arm connected to the outer end of said shaft and having a link connection with the first-named vertically-disposed arm, and a handhold on the inner end of the shaft in the Window-frame, substantially as described.

ter, a shaft passing through the tube-gearing connecting the shaft with the shutter and a handhold mounted on the shaft and arranged to interlock with either the shaft or the tube, substantially as described.

6. In a shutter-operating mechanism, the combination of the window-frame and shutter, of a tube supported for axial turning in the frame and having an open-ended slot in its inner end, a shaft supported for axial turning in the tube and projecting at its inner end beyond the inner end of the tube and having an angular surface near its inner end, a knob having a longitudinal bore angular at one end to fit the angular portion of the shaft, and cylindrical at its other end to fit over the tube, said knob being longitudinally movable on the shaft and tube, a set-screw in the shank of the knob to detachably engage in the slot in the tube, and independent connections between the tube and shaft and the shutter-' slats and shutter-hinge, substantially as and for the purpose specified.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two Witnesses.
